Application March .17, 1942, SerialNo. 435,086

1 Claim. (01. 299-131) The present invention relates to new and useful improvements in fire fighting equipment and has for its primary object to provide a spray head adapted for attaching to the end of a fire hose and designed for projection downwardly into an opening in a roof, floor, pier, deck of a ship, or other surface for suspending the spray head into a room or compartment or below the floor of a.

dock or pier, whereby to direct a spray of water for extinguishing a fire without necessitating the entrance of the firemen into the affected area.

A further object of the present invention is to provide a fire extinguisher of this character of simple and practical construction, which is efficient and reliable in performance, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view showing the spray head in suspended position through an opening in a structure and with parts shown in section.

Figure 2 is a sectional view through the spray head taken substantially on a line 2-2 of Figure 1.

Figure" 3 is a fragmentary sectional view through the coupling for the supply pipe.

Figure 4 is a longitudinal sectional view through one of the adjustable nozzles.

Figure 5 is a transverse sectional view through the supply pipe and showing the detachable collar for retaining the spray head in the opening of the structure.

; Figure 6 is a bottom plan view of the cover plate for the opening in the structure after the spray head has been removed.

Figure 7 is a sectional view through the opening in the structure and showing the cover plate in position therein.

Figure 8 1s a side elevational view of the spray head in diagram illustrating the angle of discharge of the adjustable nozzles carried in the casing of the spray head, and

Figure 9 is a similar view of a spray head designed for use under a wharf, pier or the like.

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invenerally, which is of substantially cylindrical form and rounded at each end to close the same, the spray head being composed of upper and lower sections 8 and I connected together by flanges 8 and 9 through which bolts ID are inserted. In the bottom of the lower section I is a drain plug H and projecting upwardly from the top of the upper section B is a pipe I: for connecting with a section of a fire pipe l3 by means of a conventional form of pipe coupling H. The pipe section i3 is intendedto be inserted through an opening 15 formed in a floor IE, or other structure, the pipe above the floor having handles ll formed thereon and adapted for connection with a fire hose 18 by means of an elbow 19 so that the spray head 5 may be suspended in a room or other area beneath the floor 6.

The sections 8 and I of the spray head 5 are ber 24 is provided with a spider 26 from which a valve stem 21 projects into the tubular member 22, the outer end of the tubular member 22 being flared as shown at 28 to form a valve seat for the head 28 formed on the outer end ofthe stem 21.

The nozzles 2|, formed of the tubular members 22 and the funnel members 24, are arranged in spaced relation throughout the entire areas of the sections 6 and l of the spray head 5 and are inclined, in a manner as illustrated in Figur 8 of the drawings, so that the water will be sprayed from the nozzle 5 in all directions.

In order to prevent the pressure of water from raising the spray head upwardly through the opening l5,'I providea sectional collar 30 adapted for securing in position on the pipe section I3 by ing l5 may be closed by means of a cover plate 33 having, a lug 34' on its under surface to prevent displacement of thecover plate being formed with a recess 35 having a handle 36 extending transt-lon, the numeral 5 designates; ray head genversely thereofto facilitate removing or the cover plate when it is desired to insert the spray head through the floor.

In Figure 8 of the drawings the discharge nozzles 22 are shown inclined downwardly adjacent readily understood from the foregoing without further detailed explanation.

Having thus described the invention what I claim is:

A spray nozzle comprising a tubular member adapted for attaching to a hollow body with one end of the member projecting into the body, a flared extension adiustably connected to the inner end 01 the member, said member having a flared valve seat at its outer end, and a valve carried by the extension for axial movement in the member into and out of engagement with the valve seat.
